SawLink Universal ToughMount - Wire based pole saw conversion

SawLink Universal ToughMount is a 3D printable design that securely mounts a battery-powered handheld chainsaw to a pole (recommended Ø25–32 mm), creating an extendable pruning tool with a wire-operated trigger system. It’s built for users who prefer robust assembly using standard metal fasteners like hose clamps, screws, and lock nuts — all available at any hardware store.

A 2 mm steel wire runs through the pole and connects the saw to a remote trigger, allowing precise control from the opposite end — perfect for trimming hard-to-reach branches. This version prioritizes strength and durability, ideal for heavy-duty or long-term setups.

A. Printer Settings:

• Filament Type: PETG, ASA, PET-GF or another strong material suitable for outdoor use
• Wall thickness: >3 mm
• Infill: >30% for added strength and durability
• Supports: Not required, could improve the aesthetics of some overhangs. Don’t use supports for the trigger.
• Nozzle Size: >0.4 mm (I've used a 0.6mm nozzle)

B. Assembly Instructions:

1. Chainsaw Holder Assembly:
   1. Assemble Chainsaw Holder acc. to drawing below. Use the lock nut to allow rotational movement of the lever arm. The roller shaft can be tightened harder since the roller will rotate around it.
   2. Secure the Chainsaw Holder around your handheld chainsaw. Ensure it is secured snugly with the hose clamps, as this will be the main support during operation. Depending on your chainsaw’s design, you may need to bypass the safety button that typically unlocks the trigger. In my case, I used plastic strips and a nut to keep it pressed. Attach the chainsaw and the top pole mount with 2 hose clamps. 
2. Trigger Mechanism Assembly:
   1. Assemble the Trigger control acc. to drawing below. Use the lock nut to allow rotational movement of the trigger.
   2. Attach the trigger control mechanism on the opposite end of the pole. This will be connected to the chainsaw via the Ø2mm steel wire. Make sure the wire runs smoothly and has proper tension to activate the chainsaw trigger. The wire should be fixed between the two M4 wide washers to avoid wear of the trigger.
3. Fix to pole:
   1. Secure the chainsaw holder and trigger control firmly to the pole using screws and hose clamps. Ensure the connections are tight and secure to avoid accidents during use.
4. Adjust wire tension
   1. Tension the wire enough to push the trigger but not to tight to avoid the trigger getting stuck in the on-position.
5. Adjusting pole length (if used with a telescopic pole)
   1. SawLink can easily be used with a telescopic pole. just make sure to take out the battery when adjusting the pole length and wire tension to avoid accidentally turning on the chainsaw. Always loosen the wire before adjusting the pole length
